WILLIAM S. TOTHILL, OF CHICAGO, ILLINOIS.

SWING.

SPECIFICATION forming part of Letters Patent No. 247,524, dated September 2'7, 1881. Application filed November 4, 1879.

1 0 all whom it may concern Be it known that I, WILLIAM S. TOTHILL,

.of Chicago, Cook county, State of Illinois, have invented new and useful Improvements in Swings, of which the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a front elevation; Fig. 2, a vertical cross-section; Fig. 3, a cross-section, showing methods for increasing the power of the cord. The seat shown in this fig'ure is a modification of the seat shown in the other figures. Fig. etis a front view, and Fig. 5 a side view, of the seat detached.

The object of this invention is to improve the construction and operation of the swing patented to me July 30, 1878, No. 206,406; and its nature consists in the improvements and combination of parts, hereinafter set forth and claimed as new.

In the drawings,A indicates the supportingframe; B, the swinging bars or frame; 0, the seat; a a, operating-cords; 1), eye, staple, or pin for attaching the cord; cd,pulley or sheave around which the cord passes e 6, back and front seat-posts; f, seat; 9, foot-rest; 71., lower cross-bar; i, upper cross bar or rod; j, adjusting-braces; 7c, adjusting-notches; l, retaininghook, and m pivots for the supporting-frame.

The frame A is made of four straight bars pivoted together at m, so that they may be spread or folded in pairs, and the inner ones of each pair of bars are connected by a crossbar, A, at the top, to which the swinging bars B are pivotally connected; but the pivots at m may be extended through, so as to form a cross-rod, upon which the swing may be suspended, as shown in Fig. 3.

The swing-bars B are split about three-fourths of their length, as shown, by a saw or otherwise, and are spread apart at the bottom by the bars h, to which they are attached. The bars 71. may be straight, as shown at Fig. 2, or curved in a rocker form, as shown at Fig. 5. The posts 6 e and the adjusting braces j are pivoted to the bars h, and the cross bars or rodsfi are pivotally connected with the posts 6 e. The back above the seat, the seat, and the front below the seat, are furnished with slats or upholsterin g, so thata convenient chair is formed when the posts are nearly upright, and a bed or cradle when they are nearly horizontal, and varying between the two as they are intermediately adjusted.

The adjustments are made by means of bracesj and the notches hat the back or sides of the posts 6, and the braeesj are held in place for additional safety by retaining-hooks, a convenient form of which is shown at I, which are attached to them and engage with pins on the posts, which may be provided for each notch or for a part of them. As this seat is arranged, it will be seen that it rises or falls as the back is raised or lowered.

The cord at is attached to a projecting bar at 12, passes under the sheave or wheel 0, over the sheave or wheel cl, and down to the seat, so as to be within convenient reach for the occupant of the chair.

I have shown a second cord, a, with a similar set of sheaves, so that the swing may have power applied to it in both directions of its movement, or in either direction, by taking hold of both, or one or the other of the cords. The sheaves relieve the cord from wear; but where that is not particularly desired they may be omitted and pins or eyes he substituted in their places.

The chair part of the swing is so constructed that it'may be separately used, as it is easily detached from the bars B.

The cross-bar or yoke D, as shown, is permanently fastened to the swing; but it may be so attached that it will turn for folding; but it must be practically rigid and firm in use.

What I claim as new, and desire to secure by Letters Patent, is

l. The folding frame A, having its supports in pairs, and the inner one of each pair connected together at the top,in combination with the swinging bars B B, suspended from the connecting cross-bar A, whereby the swinging bars are strongly supported and allowed free play, substantially as specified.

2. The detachable seat or chair 0, having its posts pivoted to the base-rail h, and connected together by the pivoted bars f and locking and adjusting bracesj, whereby the seatis lowered with the back, when let down,and the occupant is made to swing in the arc of a larger circle than before theseat was lowered, substantially as specified.
